Dugtrio, The Mole Pokémon. A team of Diglett triplets. It triggers huge earthquakes by burrowing 60 miles underground. They always travel together. Known to burrow more than 60 miles underground and trigger quakes. Its three heads bob separately up and down to loosen the soil nearby, making it easier for it to burrow. No one knows what it's like underground. It is actually triplets that emerged from one body. As a result, each triplet thinks exactly like the other two triplets. They work cooperatively to burrow endlessly.

Arena Trap

Strategy Using Dugtrio

Quite simply the only effective Dugtrio set. The main
reason for Dugtrio's use is because it has one of the
top traits in the game. Arena Trap acts like an
automatic Mean Look on all Pokémon excluding flyers
and levitators. This allows it to be great for picking
off injured Pokémon as well as Pokémon vulnerable to
Earthquakes.

Earthquake is pretty much the only move you'll be
using on this set. Rock Slide will rarely see any use
since you won't be switching into flying types and the
only times you'll see yourself using Aerial Ace is if
Heracross or Breloom is in play. Hidden Power [Bug] is
for KOing Celebis, who on occasion will switch into
play at the exact same time as you. Sludge Bomb is for
Grass types who resist Earthquake, but once more, you
won't be switching into many of those.

Dugtrio requires a lot of prediction skill to use
effectively. One huge asset Dugtrio has is the fact
that it traps to Pokémon that Skarmory-Blissey dread,
Tyraniboah and Magneton. If you can predict when these
Pokémon will come into play, you can trap them and
then Earthquake them away. It's also very proficient
at fainting Blissey and has the fortune of not being
1KOed by any of Blisseys attacks (including Ice Beam)
with only a handful of Special Defence EVs (this is
also based on a Blissey with a Max Special Attack
stat, which is a rarity, so you should always feel
safe to switch into Blisseys if your Dugtrio isn't
injured).

To help keep Dugtrio alive, it should be backed up
with the support of a Rapid Spinner. You'll find
Spikes is easily set up against a player using Dugtrio
since Skarmory can freely switch into it after it has
KOed something. A Wish-passer is always favoured as
well, Vaporeon being a very useful support since it
lures out electric attacks (allowing Dugtrio to freely
switch in).

[For those using Dugtrio on their Cartridge, use both
Sludge Bomb and Aerial Ace if you can't obtain Hidden
Power Bug.]

EV Corner:

EVs: 252 Atk / 216 Spd / 42 SDef
Adamant Nature (+Atk, -SAtk)

Adamant Dugtrio is the best way to go. The Speed
advantages of the Jolly version aren't enough to
outclass the ability to 2KO Blissey and 1KO
Tyraniboah. Although 252 Speed EVs are perfectly
acceptable, they aren't necessary. With 216 Speed
Dugtrio can outrun things like Jolly Slaking and Timid
Zapdos. Whatever is leftover helps support its Special
Defence, which-believe it or not-can survive a super
effective Hidden Power from Jolteon (among other
things).

EVs: 252 Atk / 252 Spd / 6 SDef
Jolly Nature (+Spd, -SAtk)

For this one, MAKE SURE you have a 31 Speed IV. This
Dugtrio has the same speed stat as things such as
Alakazam and Sceptile, although it's risky since it's
a coin toss to decide who goes first if they have max
speed. I personally don't like this distribution since
it doesn't 2KO Blissey (when counting in Leftovers) or
1KO Tyranitar, however it does have the bonus of being
able to pick off weakened Starmies and Tauroses while
KOing Raikous.

This set is basically one of the few ways to be
guarantied to beat Wobbuffet. After it's KOed
something, switch in and use Toxic. Substitute can be
used while you pass the time for Toxic to go to work
and once you've KOed Wobbuffet, you can Sub to get
Liechi activated. From there just attack things with
Earthquake and Rock Slide. It's nowhere near as
effective as the Choice Bander but if you know someone
who uses a Wobbuffet, this Dugtrio could be for you.
Use the same EV distributions as the Choice Bander for
this set.

Strategy Against Dugtrio

Prediction, that's your main strategy. Theoretically,
you can't 'counter' it since a lot of the time you
won't be able to switch into it. However, if you can
predict correctly you can make it run a lot and if you
predict when it'll come into play you can KO it.

Things you should use against Dugtrio are:

- Defensive Water types (such as Suicune and
Blastoise).
- Skarmory.
- Claydol (although watch out for HP Bug) and Flygon,
who both resist Earthquake and Rock Slide. Breloom can
as well but it's risky with Dugtrio's Aerial Ace
access.
- Things with Intimidate and solid Defence.
- Porygon2 and Wobbuffet, who can trap Dugtrio, take
an EQ from it and then KO it.
- Things like Mach Punch and Quick Attack can beat a
weakened Dugtrio.

If you can lay down a few layers of Spikes you can
severely weaken Dugtrio's abilities to switch back and
forth, since after its taken a hit it will have little
HP to spare and will most likely find itself KOed by
Spikes.

Whenever you use Jolteon and don't have a Substitute
up, always Baton Pass out (assuming you have Baton
Pass on Jolteon), since you can't KO Dugtrio with a
super effective Hidden Power. Raikous who don't have a
Modest Nature with Max Special Attack also risk not
being able to KO Dugtrio with Hidden Power, although
unlike Jolteons, they don't have a choice about Baton
Passing away.

When assaulting Dugtrio on its way into play, its
Physical Defence is a lot easier to target than its
Special Defence, but either way, it's easy pickings
for any form of decent offence.

Animé Appearences

Dugtrio has had a few Animé Appearences. First it was trying to stop the construction of a Dam. After that Poncho used it to try and herd up the Electrode that were invading an island. After that Kaede used it in her battle against Ash
